With the Flammable Gas Sensor mounted on the Elios 3, operators can reliably detect +14 fl ammable gases (including hydrogen), reducing risks during confi ned-space inspections. Factory-calibrated and equipped with built-in self-testing, the Flammable Gas Sensor requires no fi eld calibration, ensuring continuous, fail-safe operations in even the harshest industrial environments.
